Today, when I was collecting the weekly rewards, I had a trouble when collecting the raids weekly rewards. I toke two packs from list, but i could not take gold and bombs symbols (those used to buy blueprints); they disappeared.

I restarted game and now, in the raids shop screen, the "star" indicator still appears, but no items in the list.

This is a common problem GusGus, I've been hit by it a couple of times too.

If the collection page is blank, and there's still a star on the Rewards box? That's a good sign! Your remaining rewards should show up next week, along with this week's rewards too. I haven't seen it fail twice.

If there was text in the box saying you have no rewards? That would be bad, meaning they were lost & the devs would have to replace them manually.
